Excellent review as always and very impressive results. Hats off for Enermax.

They seem to have 425W modu82+ model, which should have even better efficiency curve with half the price of the 625W model. Enermax also has new Pro82+ line up, which looks exactly the same, except it's not modular. The Pro82+ 385W might be a real sweet deal considering it's sold here for only 65â‚¬. That's cheaper then Corsair VX450.

Color me very impressed. I was hopeful seeing the low rpm fan specs on the website originally, but this proves how well that works. I guess the really high efficiency and well designed fan controller really help. Now as long as there's some good signs of a solid long lasting psu(which unfortunately has not been the enermax reputation so far), this should be an unqualified buy for any new silent psu shopper.

I had the impression that enermax psu's were fairly reliable. Of course opinions change from forum to forum but I`m curious where the bad reputation comes from.

My impression too. The only reliability reputation Enermax has ever had, is up there with the very best.

Enermax finally builds a PSU that isn't a noisy piece of crap.

The Enermax NoiseTaker series was the reference round here until Seasonic pipped them.

Thanks SPCR for the review. Iâ€™ve not got time to read everything, is the Pro series exactly the same as the Modu series, apart from the modular connectors? Fancy a Pro82+ 385w, as long as it performs exactly to the standard of SPCRâ€™s test sample.

Wow, my jaw dropped and I'm drooling! Forget about Seasonic or BeQuiet, this Modu 82+ (actually better efficiency in Europe) is my next PSU.
Many thanks to SPCR! I believe the noise difference is even greater than the review listed, because of the difficulty in measuring noise at ~500rpm.
My Seasonic runs the fan at ~800 rpm, and I can hear it, but 500 rpm would be silent to me, no need for a fan swap.
I suppose the Modu 82+ sample had no buzz, because it would have been louder than the fan.
The Modu 82+ and Pro 82+ are *in stock* at Scan computers: http://www.scan.co.uk/search/search.asp ... &p=4&t=YesTo be fair to Enermax, their Infinity series was a departure from noisy PSUs, as reviewed by Xbitlabs.

Actually, there's always a buzz from every PSU, and this one is no exception. It's a question of how audible, from what distance. I wrote in the review...
From about six inches away, the acoustic signature was primarily a mild electrical buzz, audible over a very soft touch of broadband noise from the fan.

FYI, the giveaway thread and this discussion thread have now been separated. lm is right, the former was swamping the latter, which is now here.

Reachable -- That "fuzzylogic" reference is one of the weirdest I've ever come across in a PSU. The only thing I can think of is that it could be referring to a fairly high level of hysteresis to ensure the fan does not instantly change speed in response to changes in temperature.

Rules are usually expressed in the form:IF variable IS set THEN action

For example, an extremely simple temperature regulator that uses a fan might look like this:IF temperature IS very cold THEN stop fanIF temperature IS cold THEN turn down fanIF temperature IS normal THEN maintain levelIF temperature IS hot THEN speed up fan

Notice there is no "ELSE". All of the rules are evaluated, because the temperature might be "cold" and "normal" at the same time to differing degrees.

Yeah, it's going to be, at least I hope so. I'm building one from scratch, because I am a programmer and will work from home only, so because the system doubles as both the system that brings me my income and the system I use at leisure time too, I want it to be good.

You should get one from an independent vendor to recheck if it's really that good, then.

No, it's not an engineering sample. It looks nothing like an engineering sample, of which I seen many over the years. It's just that the final package did not come through a QA the way it would have if the thing was on a production line where the box, accessories and all would be the final "assembly". They didn't have a box.

Anyway, there are retail packaged samples on their way (one 625). I'll certainly check on those report if there any variances between this one and those.

Nice supply. I'd purchase 10 of the 425's in a minute if they had a reasonable cable system. Only 3 sata just doesn't make for a useful system for us. Since a modern system with one video card and 4 drives (that needs a max of 200w) is not uncommon, why do they lock themselves out of the market???

The PROD82+ 385/425 have 4 SATA connectors each, and I'm sure you could easily obtain extra detachable SATA cables for the Modu82+ series. That's the whole point of modular cables, right? (IRRC, Antec even had a PSU a while ago which came with extra DIY connectors and cable so you could make more custom ones of your own.)

I don't know who "us" is, but I'd say a system with 4 HDDs is not modern at all; it's downright primitive. With the drive capacities we have now and so many options for external storage, why in the world would you load up so many noisemakers and heaters in one PC?

I have a question, MikeC, if you're talking to an Enermax representative (or if one reads this discussion, which I am supposing they might).

Why only one 3xSATA power cord on the 425w version? 425 will power a great deal more than a super-barebones PC with three drives, but in order to get more connectors we are shunted over to the 525w version, which is completely excessive.

This, combined with the 85c instead of 105c main capacitors, is likely going to make me select the M12II-430 for my mother's new desktop over this. However, that fan performance is exceptional! I'm just not going to get another 100w of power just to have more than on drive's worth of additional connectors.
